Antibacterial Activity of The Hexane Extract from Leaf of Plant Solanum Ferox L

. Solanum ferox or Acid aubergine plants is one of the vegetables that are made in the food. Solanum ferox contains terpenoid compounds, steroids, flavonoids, alkaloids, and phenolics. Solanum ferox has antipyretic active compounds, antirheumatic, antiasthma, antiviral, and as a syphilis drug. The purpose of this research is the antibacterial activity of Solanum ferox plant leaf extract. Solanum ferox leaves are extracted using n-hexane. The extract was tested for antibacterial activity using a diffusion method to use E.coli, S.aureus and B.subtilis bacteria. Amoxicillin is used as a positive standard, whereas negative control is the solvent used to dissolve the sample. The antibacterial activity of n-hexane extract and amoxicillin showed inhibitory zone to E.coli of 7.80 - 12.93 mm and 19.97 mm, whereas in S.aureus and B.subtilis did not provide inhibition zone.
